Abstract:
The present invention relates to a method of protecting grapevine plants against grapevine yellow disease caused by the phytoplasms Bois noire and/or Flavescens doree, which comprises treating the shoots or the soil in root proximity with an effective amount of a compound (I) in which R1 is hydrogen or C1-C4-alkyl and R2 is C1-C4-alkyl or C3-C6-cycloalkyl, or agriculturally acceptable salts thereof. In addition, the invention relates to the use of combinations of a compound (I) for inducing tolerance of grapevine plants to Bois noire and/or Flavescens dorée.
Abstract:
The present invention relates to a method for treating hop plants comprising the application of an aqueous formulation containing acylcyclohexanedione of the formula I as defined below, or a salt of said acylcyclohexanedione of the formula I, onto the hop plants at their growth stage BBCH from 61 to 79. The invention further relates to a use of said acylcyclohexanedione for increasing the yield of cone mass of the hop plants. It also relates to a use of said acylcyclohexanedione for increasing the concentration of prenylated polyketides in the cones of the hop plants.
Abstract:
The present invention relates to the use of an active compound that inhibits the mitochondrial breathing chain at the level of the b/c1 complex for improving the tolerance of plants to low temperatures.
Abstract:
A method of enhancing resistibility of crop plants against bacterial and/or fungal diseases, which comprises treating the plants or seeds with low rates of 2-{1-[4-(3,5-difluorophenyl)semicarbazono]ethyl}nicotinic acid, common name diflufenzopyr, a method for controlling harmful fungi and bacteria using mixtures of diflufenzopyr and compounds Il and/or III, and also compositions comprising these mixtures.
Abstract:
The present invention relates to mixtures comprising a) a compound of the formula I in which X, m, Q and a are as defined in the description and b) one or more ethylene modulators (II) selected from the group consisting of: o inhibitors of ethylene biosynthesis which inhibit the conversion of S-adenosyl-L-methionine into 1-aminocyclopropane-1-carboxylic acid (ACC), o inhibitors of ethylene biosynthesis which block the conversion of ACC into ethylene, or o inhibitors of ethylene action, and also to compositions comprising them and to their use for controlling harmful fungi.
Abstract:
Die vorliegende Erfindung betrifft die Verwendung von Acylcyclo hexandion-Derivaten zur Verbesserung der Toleranz von Pflanzen gegenüber Kälte und/oder Frost.
Abstract:
The invention relates to the use of particular quaternary bioregulatory active agents in combination with triazole derivatives, in particular, metconazole or an agriculturally applicable salt thereof. Corresponding means are also disclosed.
Abstract:
The invention relates to agents which are based on a homogenous, aqueous phase containing at least one active substance from the class of the quaternary compounds, ethylene oxide/propylene oxide block copolymers and ammonium nitrate. Additional active substances can be incorporated. The homogenous phase is stabilised with ammonium nitrate. The invention also relates to use of these products as bioregulators.
Abstract:
Fruit yield enhancement is achieved by applying a semicarbazone in a fruit yield enhancing effective amount to the locus of a fruit bearing plant. Most preferably, the semicarbazone treatment is practiced at the onset of reproductive growth - that is, at the onset of the flowering and/or fruit reproductive growth stage of the plant. Most preferably, the semicarbazone is diflufenzopyr.
Abstract:
The present invention relates to the use of a combination of acylcyclohexanedione carboxylic acid or salts thereof and acylcyclohexanedione carboxylic acid esters for improving the development of gramineous plants. The invention also relates to a method for improving the development of gramineous plants in which the plants or plant sections thereof are treated with said combination.
